Hi there,


Yesterday, at around 8.00 a.m. (GMT +8), my IP address was listed by Barracuda as being on their blacklist. Is there any way I can find out why that is the case? I looked through my mail.log, as well as the emails sent, and I could not find anything that would cause my IP to be blacklisted. I have also set up SPF, DKIM and DMARC for all of my domains.


I sent Barracuda a removal request yesterday at http://www.barracudacentral.org/rbl/removal-request, but it still hasn't been processed, and emailreg.com is also down. Barracuda is the only banlist that has listed my IP on its banlist. Would be great if I could know why I was blacklisted, so I can rectify this issue, or if I was banned because I was in a subnet range that Barracuda has listed.

Hello Pek,


Thank you for contacting Barracuda Networks!


I have investigated the requested IP and it was blocked due a range As i couldn't see any spam activity under this, have requested for removal. Please allow 2-24hours for the changes to propagate. Going forward for any of the request removal, please do contact us through the following email address "intent@barracuda.com.
